Hour 11: Angelelli leads, GTD leaders collide

The eleventh hour was highlighted by a dramatic accident in GTD.

On the prototype side, the No. 55 Mazda slowed to a halt for a moment before taking off again, but losing a lap in the process. That same car narrowly avoided the next big accident to occur at this year's 24.

Racing through the tri-oval for the GTD lead, the unthinkable happened between Lamborghini drivers Justin Marks (No. 16 Change Racing) and Bryce Miller (No. 48 Paul Miller Racing). They collided and spun across the infield and pit lane, impacting the inside wall before sliding back across Turn 1. Both cars were forced back into the garage with the No. 48 unable to even move under its own power.

A trio of Corvette DPs headed the field on the ensuing restart with the Action Express duo trailing Wayne Taylor Racing. Scott Pruett hounded Max Angelelli for the remainder of the hour, unable to work his way by.

While trying to navigate one of the Ford GTs, BMW lost the GTLM lead as the No. 911 Porsche of Nick Tandy overtook John Edwards into the bus stop chicane. Not much has changed on the PC side, but the pole-sitting No. 20 BAR1 ORECA has gained a substantial amount of ground on the current leader -- The No. 52 of PR1/Mathiasen Motorsports.

With the Lamborghini drama in GTD, the door was opened for the Frikadelli Racing Porsche to take control.
